FUEL COMPOSITION.

To all whom it may concern:

Be it known that I, ALBERTO DILLON DE MIOHEROUX, of Marseilles, France,have invented a certain new and useful Improved Fuel and Composition forProducing the Same, of which the following is a specification.

The object of this invention is to produce an improved fuel, preferablyin the form of bricks, having coal, peat, or similar material for itschief constituent, but without sulfurous odor during combustion andhaving a high degree of efficacy for heating and lighting, while cheapand easily manufactured.

To this end I mix with water, gradually raised in temperature to theboiling-point, a quantity of one or more of the organic hydrocarbonderivativessuch as cerotic,margaric, or stearic acids-turpentine, or thes'o-called mineral oils, using one or more of these singly or mixed,whether acid or alkaline, as required. This mixture being liquefied andabout to boil, I add, while lowering the fire, protoxid of iron anddolomite, both finely powdered, and liquid lime, soda, or other alkalinesubstance or substances used by soapboilers. The dolomite is used as themost convenient way of supplying carbonate of magnesia. I stir the mass,pouring slowly'in the lime, which is the last of the ingredients. Whencooled, the mixture forms a mass which may be preserved until needed. Ifrequired for immediate use, cooling is unnecessary.

1 The coal, coke, peat, or other dense hydrocarbon fuel is preferablydried and powdered, and the mass above described is mixed there-SPECIFICATION forming part of Letters Patent No. 648,042, dated April24, 1900.

with. Bricks may be molded from the mixture thus resulting forconvenience of use and afterward coated with any suitable silicate, suchas silicate of soda. In making such bricks the mass of hydrocarbonderivative, carbonate of magnesia, and lime may be used without thecomminuted fuel and with no more than from five to ten per cent. ofcoaltar or petroleum instead; but I prefer for most uses to mix thedesiccated comminuted fuel with the other materials, as above.

The proportions preferably used are eightytwo to ninety-eight parts involume of the coaldust, comminuted peat, or other like fuel; two toeighteen parts of the cerotic acid, mineral oil,or their substitutesabove mentioned; from two to six parts of dolomite or carbonate ofmagnesia; from two to eight parts of protoxid of iron, and from six totwelve parts of liquid lime.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A composition of matter for fuel consisting of coal-dust, cerotic acid,protoxid of iron, carbonate of magnesia, and liquid alkali in about theproportions stated.

In testimony that I claim the foregoing as my invention I have signed myname in the presence of two subscribing witnesses.
